Hi , I want to create a bc file by llvm-gcc, and need to pass a input file when create this file, how can i do it?I saw options in "llvm-gcc [options] filename" but it could not help me. I have an another problem too. my program contains some C file , that main function use those, but i don't know how create bc file with regard to other file.  tanks, -------------- next part

hi how can i write IRinstruction on a file.txt? when i use  {for(inst_iterator I = inst_begin(F), E = inst_end(F); I != E; ++I,count++)  IRcodefile << std::basic_ostream(*I) <<"\n" } i get  error. is there any way that i can write it on file? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, http://www.ruby-forum.com/topic/151662#669164 Hi, Please read more on the above link first, which is available in this section of Ruby on Rails. It will give you a clear understanding of Deployment scenario The Author of that thread and Me too, are frustrated with Lack of Shared Hosting and Tough Deployment Scenario, since nothing is shaping up. We do not want to get carried away with

I haven't used MemoryDependenceAnalysis myself, but I recommend that you read its doxygen documentation:

Hi, I'm trying to do some (loop-carried) dependence analysis using LLVM, but I'm confused by the results I'm getting. For example, consider this simple C program: int main(){ for (int i = 0; i < 10; ++i) { } return 0; } I would expect that the loop comparison depends on the loop initialisation and the loop update, however I only see a dependence to the loop initialisation.

Hi, The DependenceAnalysis pass will find loop-carried dependences. However, it is a conservative analysis and will sometimes suggest there may be more dependences than actually exist. In your example, I expect the analysis is confused for some reason and is returning the default confused response. You could test it using the isConfused() method. Note that the DVEntry::ALL direction is always

Hi, Does anyone know if there is any existing code I can use to do a loop-carried dependence analysis for LLVM IR programs? I searched the mailing-list archive and it seems like someone planned to implement a loop dependence analysis pass in March. I'm just wondering if this project is ongoing/finished or if there is other projects that may have the code I'm interested in. Thanks!

Hi, I am trying to use the DependenceAnalysis pass to get the Distance vector for the innermost loop. I am in LLVM learing process. I have used the following code inside my original code to get the distance vector. It is not giving any syntax error but it is has some logical but and giving segmentation fault. void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll();

Hello, I am very new in LLVM and I am trying to understand how to use it in my project. I would like to write a Pass (?) that analyzes the loops in a program and says if the loop has a data dependence and what kind of data dependence. Do you guys have any suggestion how do to it? Thanks. Best Regards, Simone Atzeni

Hi; I was playing with the -lda pass of LLVM on the following program- #include <stdio.h> void main() { int a[10]; int i; for(i = 0; i < 4; i ++) { a[i] = a[i-1]+1; } } I run the following commands - clang a.c -emit-llvm -S opt -analyze -stats -lda a.s The output is - Printing analysis 'Loop Dependence Analysis': Loop at depth 1, header block: %for.cond Load/store

Your code is buggy. The first time through the loop, you're referencing

Hi, I'm surporiseing that the loop carried dependence analysis is not exsited ; This problem can't be resolved in the future ?

Hello everyone, I intend to build a pass to profile some benchmarks for loop carried dependencies. At first I tried looking at LoopDependenceAnalysis.{h,cpp} but the files were removed for some reason. So I continued with the DependenceAnalysis pass. But the flow, anti dependence, etc methods are only reporting sequential and not loop carried dependencies. Does LLVM support loop carried

Preston, thanks for the explanation and patch. Now it's printing the direction and distance values.

The problem might be due to the fact that da.patch file was created against revision 167549, but I am on revision 167719 (I believe the most recent one). I am not sure if this cause the problem ? But Preston may I ask you to
